dc.description.abstract	In this work ,Zinc Oxide nano particle (ZnO) were successfully synthesized by a sol-gel method, then the solution of the gum Arabic was also prepared and powred by the mortar method. The samples were characterized by UV-VIS spectroscopy technique. Then the wave length ( ) nm was plotted vrs the absorption and calculation were done to evaluate the energy gap (Eg) using the formula ( a hn ) = C (hn − Eg) 2 It shows that the energy gap of gum Arabic is found to be, Eg = (2.760) eV, for both samples. Which prove that it is a real semiconductor and its conductivity increases with the increasing of the dopants Zinc Oxide (ZnO).	en_US
